A brake 38 (see FIG. 2A) of the vehicle is electrically connected to the control device 34, and the vehicle is braked by operating the brake 38 by an occupant.

  Next, the operation of this embodiment will be described.

  In the shift device 10 having the above-described configuration, the lever 16 is rotated from the “P” position to the right and disposed at the “R” position, and the lever 16 is rotated from the “R” position to the rear to “N”. "And" D "positions in this order.

  Further, the control device 34 drives and controls the motor 22 of the restriction mechanism 20 based on the vertical position of the lock piece 28 of the restriction mechanism 20 detected by the sensor substrate 32 (sensor 32A). 24, the cam body 26 (cam gear 26A and cam 26B) is rotated, and the lock piece 28 is disposed at the lower position, the upper position, and the middle position.

  When the lever 16 is disposed at the “P” position (when the shift sensor 36 detects that the lever 16 is disposed at the “P” position), the lever 16 (knob) is operated with the brake 38 being operated. When the switch 18 is not operated, the motor 22 is driven by the control of the control device 34, and the lock piece 28 is disposed at the lower position (see FIG. 3C). For this reason, the first restricting portion 28A of the lock piece 28 restricts the first protrusion 16A of the lever 16 from turning to the right, and the turning of the lever 16 to the right is restricted. The rotation from the “P” position to the “R” position is restricted (locked).

  On the other hand, when the lever 16 is disposed at the “P” position (when the shift sensor 36 detects that the lever 16 is disposed at the “P” position), the brake 16 is operated and the lever 16 When the switch 18 is operated, the motor 22 is driven by the control of the control device 34, and the lock piece 28 is disposed at the middle position (see FIG. 3B). For this reason, the first restricting portion 28A of the lock piece 28 allows the first protrusion 16A of the lever 16 to rotate to the right side and allows the lever 16 to rotate to the right side. Rotation from the “P” position to the “R” position is permitted (unlocked).

  When the lever 16 is disposed at the “R” position (when the shift sensor 36 detects that the lever 16 is disposed at the “R” position), the switch 18 of the lever 16 is operated with the brake 38 being operated. When is not operated, the motor 22 is driven by the control of the control device 34, and the lock piece 28 is disposed at the upper position (see FIG. 4C). For this reason, the second restricting portion 28B of the lock piece 28 restricts the first protrusion 16A of the lever 16 from turning to the left, and the turning of the lever 16 to the left is restricted. The rotation from the “R” position to the “P” position is restricted.

  On the other hand, when the lever 16 is disposed at the “R” position (when the shift sensor 36 detects that the lever 16 is disposed at the “R” position), the brake 16 is operated and the lever 16 When the switch 18 is operated, the motor 22 is driven by the control of the control device 34, and the lock piece 28 is disposed at the middle position (see FIG. 4B). For this reason, the second restricting portion 28B of the lock piece 28 permits the left protrusion of the first protrusion 16A of the lever 16 and allows the lever 16 to rotate to the left side. Rotation from the “R” position to the “P” position is permitted.

  When the lever 16 is disposed at the “N” position and the “D” position (when the shift sensor 36 detects that the lever 16 is disposed at the “N” position and the “D” position), the brake 38 is operated. When the switch 18 of the lever 16 is not operated in this state, the motor 22 is driven by the control of the control device 34, and the lock piece 28 is disposed at the lower position (FIGS. 5C and 6). (See (C)). For this reason, the third restricting portion 28C of the lock piece 28 restricts the rotation of the second protrusion 16B of the lever 16 to the front side, and the rotation of the lever 16 to the front side is restricted. The rotation from the “N” position to the “R” position is restricted.

  On the other hand, when the lever 16 is disposed at the “N” position and the “D” position (when the shift sensor 36 detects that the lever 16 is disposed at the “N” position and the “D” position), the brake 38 is used. When the switch 18 of the lever 16 is operated in a state where the lever is operated, the motor 22 is driven by the control of the control device 34, and the lock piece 28 is disposed at the middle position (FIG. 5B). And FIG. 6B). For this reason, the third restricting portion 28C of the lock piece 28 allows the second protrusion 16B of the lever 16 to rotate forward and allows the lever 16 to rotate forward. Rotation from the “N” position to the “R” position is permitted.

  Here, as described above, the control device 34 controls the motor 22 to rotate the lever 16 in the left-right direction (rightward rotation from the “P” position to the “R” position and “P” from the “R” position. (Left side rotation to the position) is restricted, and the control device 34 controls the motor 22 to rotate the lever 16 in the front-rear direction (front rotation from the “N” position to the “R” position). Be regulated. For this reason, the rotation of the lever 16 in the left-right direction and the front-rear direction can be restricted by the control of the control device 34 for one motor 22. Thereby, it is possible to eliminate the need to provide a plurality of motors 22 in order to restrict the rotation of the lever 16 in the left-right direction and the front-rear direction, and the configuration of the restriction mechanism 20 can be simplified.

  Further, as described above, the lock piece 28 (first restricting portion 28A) is disposed at the lower position to restrict the rotation of the lever 16 (first protrusion 16A) from the “P” position to the “R” position, The lock piece 28 (second restricting portion 28B) is arranged at the upper position to restrict the rotation of the lever 16 (first protrusion 16A) from the “R” position to the “P” position. Therefore, the rotation of the lever 16 from the “P” position to the “R” position and the rotation from the “R” position to the “P” position can be restricted by one lock piece 28. This eliminates the need to provide a plurality of lock pieces 28 for restricting the lever 16 from rotating from the “P” position to the “R” position and from the “R” position to the “P” position. The configuration of the restriction mechanism 20 can be simplified.

  Further, the “P” position and the “R” position are shifted to adjacent positions, and the arrangement position of the lock piece 28 is changed to the lower position and the upper position, and the lever 16 (first protrusion 16A) is changed. The portion of the lock piece 28 (first restricting portion 28A) that restricts the rotation from the “P” position to the “R” position and the lever 16 (first protrusion 16A) from the “R” position to the “P” position. The portion of the lock piece 28 (second restricting portion 28B) that restricts the rotation of is changed. For this reason, even when the “P” position and the “R” position are the adjacent shift positions, the first restricting portion 28A and the second restricting portion 28B of the lock piece 28 are arranged in the left-right direction (the “P” position). The strength in the direction adjacent to the “R” position can be increased, and the restriction strength of the lever 16 from the “P” position to the “R” position (the strength in the left-right direction of the first restriction portion 28A) and the lever 16 The restriction strength of the rotation from the “R” position to the “P” position (the strength in the left-right direction of the second restriction portion 28B) can be increased.

  In this embodiment, when the switch 18 of the lever 16 is operated while the brake 38 is operated, the lock piece 28 is moved to the middle position, and the rotation of the lever 16 is permitted (regulation release). Is done. However, the lock piece 28 may be moved to the middle position only by operating the brake 38, and the rotation of the lever 16 may be permitted (restricted). Furthermore, the brake 38 may be operated, and the lock piece 28 may be moved to the middle position depending on the speed condition of the vehicle, and the rotation of the lever 16 may be permitted (restricted).

  Further, in the present embodiment, the first shift position and the second shift position are set to the “P” position and the “R” position to be the adjacent shift positions. However, a shift position may be interposed between the first shift position and the second shift position.

  Furthermore, in this embodiment, the lever 16 is rotated in the front-rear direction and the left-right direction. However, the lever 16 may be rotated only in the front-rear direction (one direction).

  In the present embodiment, the lever 16 (shift body) is rotated. However, the shift body may be rotated or slid around the central axis.

  Further, in this embodiment, the shift device 10 is installed on the console. However, the shift device 10 may be installed on the floor of the passenger compartment, the instrument panel, or the steering column.
